In the latest New Money Review podcast, I interview Richard Comotto, a specialist in repo, the multi-trillion dollar marketplace used by large financial institutions to borrow and lend money in the short term.Richard, who started his career at the Bank of England, works for the International Capital Markets Association (ICMA), for whom he has authored the ICMA “Guide to Best Practice in the European Repo Market”, its website FAQs on repo and the semi-annual survey of the ICMA European repo market, which has been running since 2000. He has also advised on the development of domestic money and repo markets for bodies such as the Asian Development Bank, the International Monetary Fund and the World Bank.
